*Three resistors with values of 3 Ω, 5 Ω and 7 Ω are connected in a circuit, as shown above. When the switch S 1 is in the position shown on the diagram only two resistors, R 1 and R 2, are connected to the 36 V battery and the current is I 1.If the switch is moved to it’s down position the third resistor R 3 is connected in series to R 1, R 2, and the battery, producing a current I 2.
